“Interested sides will have to cough up €20million to sign Sergi Roberto.”

El Mundo Deportivo has reported that both the Reds and Spurs have made enquiries with the midfielder's agent, with the two sides keen to add to their attacking ranks.

But any interested parties will need to have extravagant financial backing due to a hefty €20million release clause in the 21-year-old's contract.

Roberto joined the Barca youth programme back in 2006, with his senior team debut four years later, but has only featured for the Catalan giants in La Liga six times since then.

AC Milan have also made contact for the youngster's services, but the price-tag heavily favours a move to either Anfield or White Hart Lane.

With Roberto becoming increasingly unsettled at Barca after receiving just three chances this term from Martino, the Spain Under-21 international's decision will be based on which side can offer regular football.

Liverpool boss Brendan Rodgers will be looking to bring in more attacking-minded players, with Victor Moses' loan expiring at the end of the season and Iago Aspas set to leave in January after failing to find his feet in the Premier League.

Rodgers isn't afraid to utilise youth in his first team, with Philippe Coutinho and Jordan Henderson featuring regularly in the midfield.

Spurs manager Andre Villas-Boas will likely challenge any bid from his side's league rivals, with the north London outfit struggling to create chances from open play so far.

AVB has also made no secret of the fact that he has been scouting Barcelona's younger players, but will find it hard to offer Roberto football week in, week out, with summer signings Erik Lamela, Christian Eriksen, Nacer Chadli and Paulinho all fighting for first-team places as it is.
